Title: Optical pickup
Inventor: KAJIOKA HIROSHI
IPC: G11B7/135
Filed: 1987-10-05
Abstract: PURPOSE:To attain a small sized and light weight head by coupling a head optical system with a laser diode and a signal detection system or the like by an optical fiber for maintaining plane of polarization so as to facilitate the adjustment of the optical axis of optical components. CONSTITUTION:The light from the laser diode 1 is sent to a head optical system via the optical fiber for maintaining plane of polarization 5 and radiated on a disk 7. Part of the reflected light from the disk 7 is fed to a signal detection system via the head optical system 12 and the fiber 5 and the rest is returned to the laser diode 1. The signal detection system reads a signal of the disk 7 depending on the polarized wave rotation of the reflected light. The change in the relative phase difference between the radiated light and the reflected light based on the change in the distance between the head optical system 12 and the disk 7 is detected as a change in the radiated luminous quantity and a terminal voltage of the laser diode 1 in the phase detection system of the laser diode 1. Thus, the alignment of the optical system is facilitated and the optical pickup with small size, light weight and low cost is obtained.

Abstract: PURPOSE:To improve the foreign matter detecting accuracy and reliability of a foreign matter inspecting device by irradiating the surface of an object to be inspected with light rays from a plurality of directions and receiving the optical information formed by each light ray by an image pickup element, and then, discriminating foreign matters adhering to the surface of the object from a pattern on the surface of the object by comparing obtained pictures with each other. CONSTITUTION:By irradiating an area 22 to be inspected with a laser beam from a laser oscillation source 13, the picture of the area 22 is taken with an image pickup element 18 and the picture is stored in a picture memory 21 after processing the picture by means of a picture processor 20. The stored picture is designated as picture 31. Then pictures are taken by irradiating the area 22 with laser beams from laser oscillation sources 14-16 and stored in the memory 21 as picture 32-34. A pattern 25 formed on an object to be inspected and foreign matters 26 exist in the area 22, but the pictures of the pattern perpendicular to the incident directions of the laser beam are included in the pictures 31-34 taken from different angles. By paying attention to this point, the pattern is discriminated from the foreign matters. In addition, since the incident directions of the laser beams are limited to three and the laser beams having wavelengths corresponding to the three colors of the image pickup element are emitted, the optical information is efficiently inputted.

Title: Memory system
Inventor: HIRAI HIROSHI
IPC: G11C11/413
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent the write-in data from being written in an address different from the address to be written in originally when the data are written in a random access memory. SOLUTION: A write-in address bus signal 1 for specifying a write-in address is inputted to gate circuits 11, 12 while synchronizing with a write-in timing signal 2. Address selection circuits 15, 16 select the write-in address by receiving a normal address bus signal 13 and an inverted address bus signal 14 outputted from the gate circuits 11, 12, and the gate circuits 19, 20 output write-in pulses 21, 22 of address according to its selection. A memory cell array circuit 23 writes in the data while synchronizing with these write-in pulses. By such a constitution, the write-in timing signal controls the write-in address bus signal, and then, the outputs of the address selection circuits are made to have the period to select no address at the timing that the write-in address bus signal changes. Thus, the different address is hardly selected at the timing that the address changes.

SOLUTION: A gravel mat is embedded higher than the groundwater level of the ground, the thickness of unsaturated earth layer existing above the gravel mat is less than 1.5 m, and the upper portion of the unsaturated earth layer is practically in a state of water drainage impossible. Thus, where the allowable pore water pressure of the ground to be worked by the gravel drain method is U(tf/m2) and excess pore water pressure presumed to occur by an earthquake for t sec. in ground is u'(tf/m2), the following equations (1) and (2) ; (1) V'>=Q' (in the equation, V'(m3) shows a predetermined porosity volume such as gravel drain 2, and Q'(m3) shows the displacement from the predetermined gravel drain 2). (2) Δp<=Δu (in the equation, Δp(tf/m2) shows the predetermined air pressure increasing in the gravel mat, and Δu(tf/m2) shows U-u').  Where all are satisfied, the air vent hole installation is judged to be unnecessary.
